I may be wrong, but I thought that audioop and imageop only work in a
32 bit environment.

I found an old post by Guido (1998) asking for testers in 64-bit
environments; it seems that the work he did then (and perhaps some later
work by him or others) gave fruit.

I checked the source (of audioop at least), and there are some #ifdef
code at the start of it, assuring the type used in calculations is 4
bytes long.
The tests ran fine! :)

Oh, fine. You'll probably have to dig into setup.py to find why
they're not building on itanium -- not having one, it's not the sort
of thing I can really motivate myself about :-)

Thank God this is not a HP/UX then... presumably. See PS.

In Diablo II, it means that a Barbarian has stood over the corpse and
yelled a particular magical warcry to draw out any remaining potions
or possessions.

MH might have meant something else ;-)

Yes, MH presumably meant "Tux the Penguin" instead of "a Barbarian",
"long-term viability" instead of "potions", and "market share" instead
of "possession s". ;-)

"broken". I tried to build 2.3.1 on the HP testdrive itanium/hp-ux
machine, and the results were far from encouraging.

_tkinter built fine for me, with Python 2.3.1, on a Debian/ia64
system. If it was not built for you, most likely, you forgot to
install the header files.

audioop and imageop are not build because of this code in setup.py:

# Multimedia modules
# These don't work for 64-bit platforms!!!
# These represent audio samples or images as strings:

# Disabled on 64-bit platforms
if sys.maxint != 922337203685477 5807L:
# Operations on audio samples
exts.append( Extension('audi oop', ['audioop.c']) )
# Operations on images
exts.append( Extension('imag eop', ['imageop.c']) )
# Read SGI RGB image files (but coded portably)
exts.append( Extension('rgbi mg', ['rgbimgmodule.c ']) )

Martin

The header files were there (/usr/lib/tcl), and that is why I managed to
compile just by uncommenting the lines in Modules/Setup. I didn't
install any -devel packages in the meanwhile.
I'll give it a shot again remotely when the machine reaches our client
(we must send it tomorrow).

Ah, thank you. Given that they worked fine for me[1] on ia64, I will
post a patch tomorrow afternoon which hopefully will be used when more
success reports on 64-bit machines come in.

[1] the tests ran, and I tried the following on a Windows python, a
32-bit Linux and the ia64 one side-by-side:

print audioop.max("he llo there!", 2)

and I got 29285 in all three of them

Why are the header files in /usr/lib/tcl???? Which header files
specifically? If the header files where installed properly, they would
live in /usr/include, somewhere, either /usr/include/tcl.h, or
/usr/include/tcl84/tcl.h. setup.py would never look for header files
in /usr/lib.

My mistake, I'm sorry (half a sentence); the header files are
/usr/include/tcl*.h, and the libs are in /usr/lib/tcl8.3 .
